Application filed October 1, 1906. Serial No. 336,982-

To all 'whom it may concern:

Be it known that I, CURT Anonr Ham'rzscn, a subject of the Emperor ofGermany, residing at 37 Dickinson street, Manchester, in the county ofLancaster, Eng land, have invented a new and useful Improvement in orRelating to Devices for Spraying Fluid upon the Sur face of Paper,Textile Fabrics, or the Like, of which the following is a specification.

The improvement relates to the production of effects or designs upon thesurface of paper, textile fabrics, or the like, by means of a spray orsprays of fluid, and hasfor object to provide efficient means, ashereinafter described, whereby such fluid may be sprayed with moresatisfactory results in the obtaining of such effects or designs. Toaccomplish this and to carry out my improvement, I provide apparatus,certain forms of which are illustrated in the accompanying drawings,wherein Figure 1. is a cross section, Fig. 2. a front elevation, partlyin section, and Fig. 3. a part plan, of a spraying machine suitable forproducing designs upon wall-paper or textile fabrics, in conjunctionwith anyconvenient means for carrying or moving forward such paper orfabric, with or without stencil devices. Figs. 4. 5. and 6. show avertical section, front elevation and cross section, respectively, ofdetails of spraying nozzles. At

any suitable part in the length of the fabric or paper to be decorated,I mount one or more spraying nozzles, such as a, in communication withcolor or other fluid supply. Figs. 1. 2. and 3; show a tank or container6. mounted on rollers so as to be capable of movement into or out ofposition, along the platform 0. This container may be divided intocompartments, as indicated in Fig. 2., to enable various colored fluidsto be employed simultaneously.

To prevent the fluid settling and forming a sediment, I employ agitatorsor stirring devices mounted to revolve, reciprocate, or otherwise movewithin the body of the fluid. "In the example shown vertical shafts d.carrying blades e. are mounted within the container 1;. and are causedto rotate by means of gearing f. connected by a shaft g..to which motionis given through a pulley h. mounted on the tank side, which pulley isdriven by belt 1:. from any suitable motion shaft 1. 'm. are tubesdipping into the fluid, and in communication with the .spraying nozzlesa. The said nozzles are shown mounted on the top of thecontainer merelyby way of example.

n. are pipes and connections for the supply of compressed air to thecontainer, the junction piece 0. being provided for connection to an airpump or other suitable means of supply.

In lieu of, or in addition to the agitators e. in the container, I maycause the container itself to rock, or otherwise move so as tosufficiently agitate the fluid. For example, the platform 0. carryingthe container may be 5. and 6. Fluid is supplied from the containerthrough the inner tube m. inclosed by an air tube t. This latter isformed with a conical plug extremity resting in a corresponding seatingu. of the container b. A screwcap 1.. and washer is. effect an air tightjoint, the conical mounting at the same time permitting of free turn ofthe nozzle 0. I provide the said nozzle with a screwed head y. whichenables the distance between the fluid and air outlets to be adjusted,so as to regulate the fineness of the spray. Further adjustment of thespray may be'provided by changing the nozzle head, substituting one witha wider or narrower final outlet, as may be desired. I also provide aperforated ring 2. in the nozzle head, which may be turned to coincidemore or less with openings 2. in the head itself so as toprovide an airvent which may be increased or reduced at will. Thus the air pressurewithin the head may be maintained, reduced, or destroyed, whereby thespray may be varied in fineness or even converted into an unbrokenstream of fluid. The air pipes 11.. are capable of conveying largequantities of compressed air direct to the container, independently ofthe needs of the atomizers; and, whereas the outlet tubes. t. are ofcomparatively small dimensions, it becomes practicable-to varythe airpressure at the nozzles without materially affecting-the pressure on thefluid in the container. To shut off the supply of fluid, I mount at theextremity of the nozzle head a lever 3. pivoted at 4.

and free to be moved within a guide 5. attached to the head, so as tocover or uncover the fluid passages. If these levers 3. are connectedtogether, such as by links 6. a row of nozzles may be controlledsimultaneously. The spraying nozzles being conically mounted, asdescribed, may be oscillated to and fro, either automatically or byhand, through levers 7 connected thereto. 'If these levers are coupledtogether, it is obvious that simultaneous oscillation of a row ofnozzles may be effected. It is clear also that certain nozzles may beselected for simultaneous operation, whether in the same row or not.Oscillation of the nozzles during the spraying operation may bepreferred in some cases .where an equal distribution of fluid isdesired.

I would have it understood that I do not broadly claim, as new, inspraying apparatus, either a fluid container provided with agitators andsupplied with romprvsscd air, or the opening and closing of the outletsol spraying nozzles, 01' sprays-rs provided with means l'or reducing orremoving air pressure therein.

1 claim 1. Apparatus for spraying fluid. comprising a fluid container h.fluid agitators 1' mounted within the same; gearin: for o wraling andconnecting said agitators, mounted nu tho (Hillilllltl'l air supplypipes 11. 0. leading: directly into said container: fluid outlet tuhcsm. projecting through the upper part of said container; air outletnozzle iuhrs I. surrounding;- said fluid tubes, and leading: from theinlorior of said container, substantially as set forth.

2. In combination, a fluid container, a bored conical seating 11. onsame; a fluid tube m. passing through said bored seating; an air tube t.surrounding said fluid tube, and having a coned surface fitting saidconical seating; and a screw cap I. engaging said seating, and coveringavid coned surface, substantially as set forth.

3. in combination, a sprayer nozzle, having compressed air and lluldpassages. a perforated head on said nozzle, and a perforated ringmounted on said head, substantially as herein set forth.
